WALTER J. BARRON, OF NEW YORK, N. v Assicnon To AMos DENSMORF, OF MEADVILLE, PENNSYLVANIA, AND o. GODFREY PATTERSON, on NEW YORK, N. Y.

TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 376,701, dated January 17', 1888. I Application filed December 6, 1886. Serial No. 520,832. (No model.)

To (LZZ whom it may concern:

Be it known that I, WALTER J. BARRON, a citizen of the United States, residing at New York city, in the county of New York, State of New York, have invented certain new and useful Improvements in Type-Writing Ma chines, of whichthe following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in type-writing machines in which the type-bars are free at one end and carry at said end a type, and at the other end have a connectingrod which in turn connects with a key-lever,

t5 the fulcrum being near the connection of theconnecting-rod and type-bar; and the objects of my improvement are to provide simple and inexpensive means to connectthe type-bar adjustably to the hanger, and also to the fingerzo bar,s0 that the pressure of the operators finger upon the latter will cause the letter on the free end of the type bar to strike a sharp blow on the paper and in the proper location.

To obtain these essentials, the journal of the type-bar must be of peculiar construction. Its

frictional surfaces should be conical and be proportionallylarge and under control ofsome device whereby the friction can be regulated even'after the hanger is attached to the machine, and the connecting-rod should be easily adjusted and separable from the type-bar.

Various forms of j oints have heretofore been used-as, for example, in the patent granted to O. L. Sholes,No. 207,557, in which eachtype-bar 5 has conical bearings whichare journaled in hangers having spring-jaws provided with QOneshapedjOurnaIs; but the pressure thereon cannot be adjusted after the hanger is attached to the machine.

0 My invention consists in a type-bar and its .hanger ofsheet metal, the body or jaws of which are flexible and provided with conical journals and bearings produced .by punching the metal and conic-ally bending the metal 5 surrounding the punched portion and uniting the parts adjustably at these points.

It also consists in providing a type-bar with a hook upon the end of its short arm and integral therewith, from which the connecting 5o rod can be easily removed.

I It also consists in providing either one or 1 both ends of the connectingrod with a pair of spring'fingers, one finger carrying ajournalpin rigidlysecured thereto, and-the opposite finger having a perforation to loosely receive the end of said pin.

In the accompanying drawings, Figure 1 represents a perspective view of a type-bar hanger,,a type-bar, and its connecting-rod constructed in accordance with myinvention. 5o Fig. 2 is a longitudinal vertical section of sald I gers having a connecting-pin secured thereto in accordance with my invention. Fig. 8 is a side View of the lower end of the connecting rod and the spring-fingers uniting it to the swivelvlink and screw used to support the strap ofa finger-bar of a type-writing machine. Fig. 9. shows a type-bar and hanger united by a tubular rivet.

In said drawings, A represents a type-bar hanger of sheet metal, cut either in "the form of a straight strip and bent halfway of its 8 5 any toward the inner side to form a conical bearing for the conical parts a? of the hanger; andwhether the hanger embraces the typebar, as shown in Fig. 2, or is embraced bythe type-bar, asshown in Fig.3, the conical bear- Fig. 6 represents one form ofcon- 7o ings produced are of the same nature and proportionally large to prevent lateral oscillation of the type-bar when in use.

To further connect the type-bar with the hanger at its pivotal points and permit the position of these parts to be relatively adjusted at any time on account of the wear, a screw, 0, is inserted through the perforations a I), so that its conical head rests within one of the conical recesses in one of the branches of the hanger or of the type-bar, as the case may be, and its screw-threaded end is in engagement with the screw-tapped perforation in the opposite branch. A small drop of solder may be placed in the outer concavity before it is screw-tapped to permit a larger number of screw-threads to be tapped in the last-men tioned branch. The screw 0 has a small transverse perforation, 0 about half-way of its length, to permit the temporary insertion of a tine rod to rotate the screw and regulate the amount of friction of the bearings upon each other without disconnecting the hanger from the machine; but as this disconnection is often an easy matter, a rivet may be used in place of the screw 0, as the conebearings furnish such large wearing-surfaces that it will take a long time for these parts to become loose by wear, and I prefer to make this rivet 0 either with concave ends or tubular, so that by a few blows with a hammer upon the ends of said rivet they will be swaged or reset as when they were first united.

To facilitate theprompt disconnection of the connecting-rod D from the typebar, the latter is provided with a hooked tail; or, in other words, its short arm terminates in or is provided with a hook, a forming therein a recess for the reception of the upper end of said connecting-rod. Various forms of connectingrods may be used in connection with said hooked end. The rod, for example, may have an eye, d, as shown in Fig. 6; but as this construction would require the rod to be first elevated and then moved rearwardly in some very contracted locations, I prefer to secure to the upper end of the rod D springfingers (1 One of the fingers has formed integral therewith or rigidly riveted thereto a pin, (1", that extends transversely and enters or passes through a perforation in'theupper end of the opposite finger. By this construction the connecting-rod can be easily separated from the type-bar by forcing the fingers apart, and as the pin d is permanently secured tonne of the fingers and remains extended horizontallyin the space between said fingers, even after they are spread apart, all accidental disconnection of the connecting-rod from the type-bar is prevented.

To facilitate the disconnection of the lower end of the connecting-rod from the nut E, said a screw, 6, that is pivoted to the strap F, generally used to support a finger-bar.

I am aware that the short arms of type-bars have been provided with a transverse pin rigidly secured thereto, the ends of which entered perforations in the upper end of the fingers secured to the end of a connecting-rod, and do not claim said construction.

Having now fully described my invention, I claim- 7 1. The combination of a type-bar hanger, consisting of a bent strip of sheet metal having perforations in its ends and the edges of said perforations forced laterally, with a typebar having the portions adjacent its pivot consisting of sheet metal having perforations and the edges of said perforations forced laterally, whereby relatively larger conical bearings are produced, substantially as and for the purpose described.

2. The combination of a type bar hanger, consisting of a bent strip of sheet metal having perforations in its ends and the edges of said perforations forced laterally, with a typebar having the portions adjacent its pivot consisting of sheet metal having perforations and conicaljournal-bearings around said per forations, and a pin or screw passing through the perforations of the type-bar and its hanger, substantially as and for the purpose described.

3. The combination of a type-bar, a connecting-rod, and a nut with springfingers uniting said rod and nut, one of the fingers having permanently secured thereto a pin, the free end of which enters a finger perforated substantially as andfor the purpose described.

4. The combination of a type-bar hanger, consisting of a bent strip of sheet metal having perforations in its ends and the edges of said perforations forced laterally, whereby conical cavities are formed therein, with a type-bar and a pin passing through said type-bar and hanger, and having its ends conical or expanded to fit within the conical cavities of the hanger, substantially as and for the purpose described.

In testimony whereof I aflix my signature in presence of two witnesses.

WVALTER J. BARRON.
